Tea Party group calls out John Cornyn for lack of effort in Obamacare fight

One of the nation’s largest Tea Party groups is again blasting Sen. John Cornyn for not “doing everything he can” to defund the health care law.

FreedomWorks pushed out digital advertisements this week claiming that Cornyn backed away from an attempt by another Republican, Sen. Mike Lee, to threaten a government shutdown unless Obamacare funding is scrapped.

They pointed to Lee’s letter earlier this month, which dozens of lawmakers signed and promised not to support a budget this fall that included cash for Obamacare programs.

“Now some are getting cold feet,” FreedomWorks wrote. “Senator John Cornyn – one of the original supporters – has bowed to the Republican Establishment and no longer wishes to help Senator Lee. Why is Senator Cornyn withdrawing his support for Mike Lee?”

Cornyn was one of 17 Republicans to co-sponsor fellow Texas Sen. Ted Cruz’s bill to pull funding last month.

But his spokeswoman Megan Mitchell said Cornyn does not support a government shutdown because if Congress does not reach a deal on spending, “most of Obamacare would still be funded, and we would still have the same problem on our hands,” she told Texas on the Potomac.

Cornyn, who is up for reelection next year, recently hired a campaign manager from FreedomWorks – a sign he is looking to bolster support from the far right. He does not yet have a substantial Republican challenger for the seat.
